What is Cryptography?

Cryptography is the scientific discipline that aims to create secure communication systems. It is a branch of mathematics that deals with encoding and decoding information. Cryptography is used to create secure communication systems, such as encrypted networks and digital signatures. There are two main types of cryptography: symmetric cryptography and asymmetric cryptography. Symmetric cryptography uses a shared key to encode and decode information. Asymmetric cryptography uses different keys to encode and decode information.Läs mer
